Predicted to enable several functions, including cyclin-dependent protein serine/threonine kinase activator activity; histone binding activity; and ubiquitin binding activity. Predicted to be involved in regulation of mitotic cell cycle. Predicted to act upstream of or within fibroblast proliferation; mitotic cell cycle phase transition; and regulation of DNA-templated transcription. Predicted to be located in nucleoplasm. Predicted to be part of SCF ubiquitin ligase complex and cyclin-dependent protein kinase holoenzyme complex.
RGD Description
CKS1B protein binds to the catalytic subunit of the cyclin dependent kinases and is essential for their biological function. The CKS1B mRNA is found to be expressed in different patterns through the cell cycle in HeLa cells, which reflects a specialized role for the encoded protein. At least two transcript variants have been identified for this gene, and it appears that only one of them encodes a protein. [provided by RefSeq, Sep 2008]
